A Novel Technique of Endoscopic Vein Harvesting With Preserved Perivascular Tissue.

The no-touch saphenous vein harvesting technique is considered to be the ideal procedure to achieve the best quality of vein, whereas the endoscopic vein harvesting (EVH) technique is considered to be ideal for decreasing wound complications. We developed a new technique of EVH with perivascular tissue preservation. This procedure was performed by dissecting the immediate anterior and posterior perivascular connective tissues of the saphenous vein followed by cutting approximately 1 cm laterally from the saphenous vein with the use of a harvester (MAQUET Getinge Group, Getinge AB, Göteborg, Sweden). Histopathological examination revealed preserved perivascular tissue and intimal folding.
